why doesn't "which ruby" output anything?

0

I'm using Debian 6. I uninstalled ruby1.8, and then I installed ruby1.9.1.

If I type "which ruby" at the command line, it doesn't output anything. It seems like it doesn't recognize it.

Also, you might try locate ruby to see where it is, and echo $PATH to see what directories are searched for executables. – Phrogz – 2011-12-07T23:45:47.493

Ruby installs on Debian/Ubuntu don't seem to generate the symbolic /usr/bin/ruby link to the specific install you have (theoretically, so that you can have multiple versions installed point to whatever version you want to use as your default).

so...

sudo ln -s /usr/bin/ruby1.9.1 /usr/bin/ruby

should get you rolling. If which ruby1.9.1 is returning a different path to 1.9.1, then use that instead.

That's what I ended up doing http://ubuntuforums.org/showthread.php?t=1544088 It just seems that this part of the link is wrong, change ruby-dev1.9.1 to ruby1.9.1-dev
